Summary: A new strategy is introduced to synthesize 3D interconnected mesoporous biomass-derived carbon using mesoporous silica as the template. Pinecone-derived carbon is successfully synthesized using mesoporous silica KIT-6 as the template. Different chemical reagents, H3BO3, K2CO3, and KOH, are employed to prepare chemically activated pinecone-derived carbons. The template-assisted pinecone-derived carbon exhibits excellent discharge capacities and long-term cycling stability in lithium-ion batteries, while also showing great potential in sodium-ion batteries.

Summary: This study focuses on the design and failure analysis of a silicon (Si) anode for lithium-ion batteries (LIBs). The volumetric energy density of the Si anode depends heavily on factors such as Si/C loading, anode calendering density, first-cycle coulombic efficiency, and anode capacity density. Stable Si/C electrode structure is crucial for long-term cycling, and the degree of prelithiation needs to be balanced with cycle life.
